ALA Plays Key Role in Omega-3 Benefits

September 17, 2008: 04:40 PM EST
A daily 2.4 gram dose of ALA-rich flax oil is enough to raise overall levels of omega-3 fatty acids, suggests a new study. Researchers from the University of North Dakota and the University of Manitoba found that flax oil, rich in alpha-linolenic acid (ALA), could increase red blood cell levels of eicosapentaenoic acid (EPA) and docosapentaenoic acid (DPA), but not docosahexaenoic acid (DHA). ALA has received significantly less study from scientists and less attention from consumers than the longer-chain EPA and DHA. The health benefits associated with ALA include cardiovascular effects, neuro-protection, a counter to the inflammation response, and benefits against auto-immune disease. It is the only form of omega-3 regarded as “essential” to the diet, according to a recent review by Aliza Stark and Ram Reifen from the Hebrew University of Jerusalem and Michael Crawford from London Metropolitan University.
